Our boat house lifts can be installed with one or two electric motor lift systems. Hoist load is dependent on the boat house construction and the weight of the vessel. Drive units are side mounted for easy maintenance and elimination of grease dropping on the boat, as with center mounted drives. Overhead beams mount on the top plate along side rafters or directly on top of pilings. Pulleys and drive shaft attachments are welded to overhead beams adding to the level of the quality of the boat house boat lift.
